' AUTOMATIC Fransen,

To all whom it may concern:

Be it known that-I, PUL MAUsER, royal privy commercial councilor,subject 'of the l*Kin of Wrttemberg, yat Oberndorf-ontheeckar, in theKingdom of Wilrttemberg, German Empire have invented cer# tain new anduseful Ijmprovements in and vRelating to Automatic Firearms, of whichthe following is' a specification.

the kind described iii the specifications of Patents Nos.. 943,949' and.971,061 Qbjece,

being the special arrangement of the locking means vcovered by thesepatents'which has proved'tov be suitable and advantageous in View of thepe'culiarity of the vveapony as a .self-loading pistol with breechcarriage operate with aA lower projection from the block which movesbetween' them, the advclosed and cocked partly in section.l Fig; 2-

To facilitate adjustment` by hand, a separate member 'is' alsoprovided which engages with the slide and is rockably mounted directlyin the trigger guard so that lwhen the weapon is grasped it'can/bereadily seized with one fingen 4An embodiment of the invention is illus-The inventionv relates to'a recoil loader of` trated in the accompanyingdrawing, in.

In the extension g1 of the grip g which lengagesbeneath the barrel inthe known (Fig:` 5). Two retaining members b are Specication of LettersFatenc. 'Patented D131-, 31, 1914, Application tiled December 26, 1912.Serial No. 738,634. v

l members b are controlled by the slide s in such 'a manner .that in therear position of this slide (Fig. 2) their front ends are directedinward and support a projection o1 of the breech block 'u from behind,thereby locking the breech block in closing position. .In this positionthey are held by the spring -s2 .of the slide s. On ring, the slide seiiects a 'relative forward movement owing to its inertia inv oppositionlto the action ofV its spring, the supporting members b being turnedoutward so Athat the projection o1 of the breech block is able to. movebackw rd between them. In order to effect by` heidid this unlocking lofthe breech block which takes place automatically on firinga member /c isrotatably mounted in the trigger guard and engages by means of a' rib701 in a corresponding recess e3 in the slide. By press ving on thefront face of this pressure member the slides is pressed forward,whereby the retaining members b are set in the open position.

The mounting of the slide and of the retaining members intthe forwardextension of the grip and the arrangement in the triggerguard oftliemember coperating with the slide is particularly advantageous4 forpistols because it renders it possible to unlock the breech readily andconveniently in the grip position.

lVhat I claim as my invention and desirel to secure bypatent is l. In arecoil operating pistol, the combination of a frame comprising a grip, a

breech-block, locking-levers for said breech- 1 block, and a recoiloperated slide for actuating said locking-levers, said lockingr leversand said slide being located in the forward part of said frame in frontof said grip.

2. ln a recoil operated pistol, tliecombination of a frame comprising agrip, laA

breech-block, locking-levers for saidbreechblock located in the forwardpart of said frame in front of said'grip, a projection on the front endof said breech-block extendin between said locking levers and adapted tbe engaged by said locking levers to flock y said breech-block, and a reil operated slide for actuating said lookin -levers j 3. i n a recoiloperated irearm, the combination of a breech-block, locking-levers foi`said breech-block, a recoil operated slide for actuating saidlocking-levers, a spring acting upon said slide to cause the same tomove said locking-levers tol locking position, and means adapted tobemanually operated for moving said slide against the pressure of saidspring to move said locking-levers to unlocking position.

4. In a recoil operated firearm, the combination of a breech-block,locking levers for said breech-block, a recoil operated slide .foractuating said locking-levers, a spring acting upon said slide tooausethe same to move said locking-levers to locking position, and apivoted lever adapted to be Amanually operated `for moving said slideagainst" thepressure of said spring, to move said lock-ing' levers tounlocking position.

5: In' a recoil-operated pistol, the combination ofa` frame comprising agrip, a

' breech-block,l locking-levers for said breechbloclfr, arecoil-operated'slide for actuating said locking-levers, a spring actingupon said slide to cause the same to move said 'locking-levers tolocking position, means adjacent said grip and adapted to be operatedby'a finger of a user When the firearm is vheld bythe grip, said meansyoperating to movesaid slide' against the pressure of said spring tomove said vllocking levers to unlocking position. V` p 6:; Ina'iecoil-operated pistol, thecombination of'a Aiframe comprising a"grip, a

breech-block, locking-leversfor said breeclibleek, a recoiloperatedslide for actuating said locking-levers, a spring acting uponsaid slide to cause the same t0 move said locking-levers to'locking-position, and a -pivoted lev'er adjacent said grip and.adaptblock, a recoil-operated slide for actuating said locking-levers,said locking-levers and v said slide being located in the/forward partof said frame in front of said grip, a spring acting upon said slide tocause the same to move said locking-levers to locking position, andmeans adjacent Asaid grip .and adapted to be conveniently 'operated byalinger of a user when the firearm is held by the grip, said meansoperating tomove said slide against the pressure of said 'spring toFmove said locking levers to unlocking poi sition. i
